No, At that point it is easier to shim the flywheel forward and use shins. That allows you to use whatever clutch and bell that you want.
BuKu in a truggy can be a bit of a handful as far as setting them up goes. It can be done on slick tracks with the stagger or you can run all three shoes the same on higher bite. Either way it's really easy to overheat them. Werks or M2c 4 shoe. The stock clutch works fine. Make sure you have someone help you seat the shoes in and try it, I think you will like it just fine.
I am fortunate because I race with Brian who is head of Sales for Buku and has taught me how to set it up and use properly. I havent had any slipping or over heating issues. I use staggered settings. Honestly, like i said i think a lot of guys have bad experiences because they use old bells or dont set them properly because mine have been great!
